alarm-controller

A daemon to activate or deactivate alarm when a smartphone is on bluetooth range.

The daemon look for the target every 10s.

When it detect the entry of the device in the bluetooth reception area, it execute the ''entry'' script.

When it detect the device is leaving the area, it execute the ''leaving'' script.

To test the smartphone presence we send a SDP request to the bluetooth mac address of the device and request the description of the service '''UUID: Service Discovery Serve.. (00001000-0000-1000-8000-00805f9b34fb)'''

You can use bluetoothctl to check the mac adress of your device

Make your device detectable, then

$ bluetoothctl

Build and Install

• To build the project (work fine on raspberri pi with raspbian, and centos)

make

To create a configuration file:

./alarm-controller -a create -f myconfig.cfg

To test it, run :

./alarm-controller -u -a start -f myconfig.cfg

• Install

sudo make install

The software will be installed in /opt/alarm-controller

The configuration file is /opt/alarm-controller/etc/alarm-controller.conf

Change the target value to the bluetooth mac address of your device

A service file as been put in /etc/init.d, to start the daemon automatically :

sudo update-rc.d alarm-controller defauls

Using ICMP request

With ''bluetooth'' set to off in the config file, the daemon will use ICMP request instead. Then target as to be the IP address of the device.
